Former Alaska Gov. Sarah Palin (R) will attend a Tea Party Tax Day rally in Wisconsin this Saturday, according to an adviser. 

The potential presidential candidate is expected to be at the event sponsored by Americans for Prosperity Wisconsin, a Tea Party organizer.

Rebecca Mansour, an adviser to Palin, confirmed her appearance on Twitter Thursday: "Yes, @SarahPalinUSA will be at the rally in Madison, Wisconsin, on Saturday."

Palin's appearance represents a slight change of pace — her political travel in 2011 has been relatively light compared to other potential 2012 GOP contenders, leading observers to speculate that she is becoming less interested in running for president. 

The 2008 vice presidential nominee did travel overseas to India and Israel last month, but she has not hit the ground hard in key early primary states such as Iowa, New Hampshire and South Carolina in recent weeks. 

But Wisconsin's significance has increased ever since the the heated debate over GOP Gov. Scott Walker's controversial union law there, which served as a proxy argument over fiscal issues nationally. 

Palin joins a litany of other potential candidates who are appearing at Tax Day events around the country.
